Is liquid helium boiling a physical property?
Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.
What is the word equation for liquid helium?
There is no word equation, except that helium will exist as liquid phase in liquid helium
Is helium gas a pure substance or mixture?
Helium is pure as it is on the periodic table.
True or false the state of a substance depends on the amount of thermal energy it possesses?
True. The state of a substance, such as solid, liquid, or gas, depends on the amount of thermal energy it possesses. Increasing thermal energy can change the state of a substance, such as melting a solid into a liquid or evaporating a liquid into a gas.
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
Which liquid boils the quickest?
Liquid helium in the helium I phase boils at about 5 K, lower than any other substance. (Liquid helium in the helium II phase does not boil, it simply evaporates. Helium is truly weird stuff at very low temperatures.)

What substance has the lowest viscosity?
Water is the liquid that has the lowest viscosity and helium is the gas that has the lowest viscosity.
Is helium gas a pure substance or mixture?

Is helium gas substance or mixture?
Helium gas is a pure substance
Is helium gas a mixture or substance?
Helium gas is a pure substance
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
Is the helium in a balloon a substance or a mixture?
Helium is an element (and therefore a pure substance) yes
Would it be true to say that solidfication is from a liquid to gas?
False. Solidification when a substance that is in a liquid changes phase to a solid.
What would happen if you poured liquid helium into liquid nitrogen?
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
